BOTTLE-CLosuRE.

SPECIFICATION forming part of Letters Patent N0. 759,496, dated May 10, 1904.

Application led August 2l, 1903; Serial No. 170,337. lNo model.)

OoNsTINn GALLAei-inn, citizens of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented new and useful Improvements in Bottle-Clo sures, of which the following is a specification. This invention relates to a bottle-closure of that class wherein a valve is primarily disposed in the bottleneck and serves to automatically close entrance to the neck when the bottle is upright, but freely opens when the bottle is arranged at an angle during pouring or parts thereof are opened after original preparation to enable a purchaser to become apprised of an attempt to substitute some liquid other than that originally contained in a bottle.

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a transverse vertical section of a bottle embodying the features of the invention and shown completely closed. Fig. 2 is a similar view of a bottle, showing the improved closure open, so that the original contents of the bottle may be dispensed therethrough. Fig. 3 is a detail perspective view of a valve forming part of the closure. Fig. 4: is a detail perspective view of a valve-casing immovably held in the bottle-neck. Fig. 5 is a plan View of a softsolder or analagous ring used for securing the valve-easing in the bottle-neck.

Similar numerals of reference are ernployed to indicate corresponding parts in the several views.

The numeral l designates a bottle of any ordinary or preferred form, having a neck 2. In applying the improvement to the bottle very little change in the structure is necessary, and, in fact, it is only necessary thata circumferential shoulder 3 be formed on the interior of the neck a short distance above the continuation of the neck into the upper portion of the bottle-body and the provision of a groove 4 above the shoulder for a purpose which will be presently set forth. Aside from this shoulder and groove no changes are required in ordinary bottle constructions to receive the closure.

The closure comprises a tubular valve-casing 5,0f suitable material, which tapers toward its upper extremity, the wall of the casing being of compound-'curved contour. Avalve 6 is disposed in operative relation to the valvecasing and comprises a body 7 ,freely movable through the upper reduced end of the casing 5, and a head-fiange 8 to close down over said upper end of the casing. Depending from the bottom of the body 7 are arms 9, having lower outturned angular ends l0, which have a combined lateral extent materially greater than the upper portion of the valve casing, but less than the lower end of the casing. The iianged head 8 is of a diameter just equaling that of the casing 5, so that there is no projection outwardly beyond the upper end of said casing. The closure also includes a lower cork stopperll and an uppersecondary sealing-stopper l2 of usual form.

The valve-casing 5, containing' the valve 6, is first inserted in the neck 2 until the lower end of the casing firmly bears on the shoulder 3, the thickness of the casing and the width of the shoulder being precisely equal. Before the casing is secured in place or applied, however, it will be understood that the secondary stopper 1l will be shoved downwardly through the neck Qadjacent to the shoulder 3, and when the valve-casing 5 is placed in position in the neck the lower end thereof is forced over the upper extremity of the said stopper 1l, so that a part of the latter is primarily held within the casing and the valve 6 is raised, as clearly shown by Fig. l. A ring 13, of soft solder, is then inserted in the neck and disposed adjacent to the groove 4. A tubular soldering implement in heated condition is next inserted in theneck over the valve-casing and in contact with the ring 13 of solder to melt the IOO latter and produce a circumferential key to hold the casing against movement or withdrawal. The stopper 12 is then placed in the upper extremity of the neck 2 and the closure is complete. serted it will be understood that the bottlebody will be iilled up to about the point shown, and by next inserting the secondary stopper 11 the contents of the bottle will be prevented from contamination or molestation during the application of the valve-casing and Valve. When the contents of the bottle are desired to be used', the stopper 12 is Withdrawn and a downward pressure exerted on the head 8 of the valve 6. This downward pressurel forces the stopper 1l into the body of the loottle and clears the valve-casing, so that the contents of the bottle may be poured out at will. The stopper l1 remains in the bottle and will always indicate to the user under normal conditions that the original contents of the bottle are presented to him. In dispensing the contents of the bottle an angular position of the latter will cause the valve 6 to move outwardly in the casing 5 and permit the liquid to escape through the neck. Vhen the bottle is again ar- Before the closure is in may be resorted to without in the least departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is- 1. The combination with a bottle, having a neck, of a tubular valve-casing secured in the neck, a stopper partially held in saidl casing, a valve in the casing above the stopper, and a second stopper inserted in the upper extremity of the neck.

2. In a bottle-closure, the combination with a bottle having a neck formed with a circumferential shoulder and a groove above the shoulder, a stopper primarily held in the lower portion of the neck adjacent to the shoulder,

a tubular valve-casing having its lower end secured against the shoulder. said casing tapering toward its upper end, a valve loosely held in the said casing,and a sealing-stopper for the upper end of the neck.

3. In a bottle-closure, the combination with a bottle-neck having an interior shoulder 'and groove adjacent to the latter, avalve-casing held against said shoulder, a circumferential key engaging thegroove and casing, said casing being tubular and reduced toward its upper end, and a valve slidably mounted in the said casing and provided with arms having outturned extremities to prevent disengagement of the valve from the casing.

In testimony whereof we affix our signatures in presence of two witnesses.
